The cost-effectiveness acceptability frontier (CEAF) is a graph summarising the uncertainty around the cost-effectiveness of the interventions compared in a model, by indicating which strategy is economically preferred at different threshold values for cost-effectiveness. Similar to the cost-effectiveness acceptability curve, the graph plots a range of possible cost-effectiveness thresholds on the horizontal axis against the probability that an intervention of interest will be cost-effective (at the given threshold value) on the vertical axis. As the threshold increases the economically preferred treatment changes, the switch point being where the threshold value increases beyond the relevant ICER reported for the intervention of interest. This type of presentation is particularly useful if there are three or more alternatives being compared, in which case there may be two or more switch points at different threshold values.
